A plurality of cross bars 130 in the form of rods or screws And welded to form several drainage holes 140 between the bearing bar and the bearing bar and between the crossbar and the crossbar.

The conventional manhole cover installed at the entrance of the manhole is configured to have a plurality of drain holes so that rainwater or the like can be drained in a circular or square shape corresponding to the entrance of the manhole.

However, as described above, the drain hole cover or the manhole cover provided at the entrance of the manhole such as the sewer or the drain hole can filter out relatively bulky foreign substances and at the same time, the rainwater and the sewage can be drained smoothly. The odor generated in the inside of the manhole is released into the atmosphere, which adversely affects passers who pass through the upper part of the manhole such as a sewer or a drainage hole, and also causes pollution of the atmospheric environment.

In order to solve this problem, a device for blocking various types of malodors has been proposed. However, there has been a problem in that the structure is complicated and the manufacturing cost is high as well as the manufacturing cost.

Thus, the present applicant filed and filed a registered application No. 10-0893872 entitled "Drain cover for preventing malodour from manhole, " filed and registered so as to have a simple structure and to block odors and smooth drainage.

This will be described with reference to FIG.

In addition, In addition, both side surfaces are also opened and closed so as to smoothly discharge a large amount of water, such as heavy rainfall or rainy season, so as to maximize the amount of drainage and to drain water smoothly irrespective of the drainage amount.

Hereinafter, the present invention is a modified version of the "manhole drainage cover for preventing bad odors ", which is a modification of the present application. Normally, the malodor rising from the manhole is blocked and a large amount of water rapidly drained during rain or shaking is freely drained. The structure of the malodor preventing drain cover capable of reducing the back flow pressure is made simpler, and the malodor is developed so as to cut off the odor as much as possible.

Accordingly, the present invention is directed to a method of controlling a malfunctioning drainage cover, which is capable of reducing odors coming from a manhole and draining a large amount of water rapidly blown in rainy weather, The purpose of the present invention is to reduce the number of manufacturing steps and eliminate the residual stress by changing the weight to a simple structure.

Hereinafter, the configuration and operation according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description with reference to the accompanying drawings, the same reference numerals denote the same elements regardless of the reference numerals, and redundant description thereof will be omitted. The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another.

As shown in FIGS. 5A to 5C, the basic structure of the malodor-preventing drainage cover 10 according to the present invention is such that the upper surface of the drainage cover 10 is raised by a step formed at the entrance of the manhole in the upper rim and the drainage cover, And a lower portion of the inflow space is formed with front and rear surfaces 16 and 17 and both sides 18 and 19, A drainage plate 20 is formed which is closed after the bottom surface is opened and closed by a load of water introduced through the inflow space. The drainage plate is provided with a pressure reduction unit 30 for reducing backflow pressure by discharging water, The drainage cover 10 integrally provided with the drainage cover 10 is installed between the manhole covers such as the sewer port and the drainage port to block odors generated from the manhole and to smooth drainage.

However, as shown in the enlarged view of FIG. 5A, the lower end of the split projection 14 formed in the middle of the front and rear surfaces 16 and 17 of the inflow space 15 and the opposite ends of the hollow portion 14a And one weight weight 40 for returning to the original state the drain plate 20 which is coupled to the first hinge P provided at the both ends of the lower end of the split projection 14 and opened and closed by the pressure of water introduced from the outside And it is a feature of the present invention.

The weight weight 40 is generally formed in a circular shape, but may be formed as an ellipse if necessary, and may be provided with a core of a metal for increasing a load.

In addition, as shown in the enlarged view of FIG. 5A, the weight plate 40 is integrally formed with the drain plate 20 at both ends on the upper side.

At this time, it is important to determine the position of the drain pan 20. Since the load of the weight weight is reduced when the center pipe is formed at the center or the lower part, it is preferable that the weight is placed on the upper part.

The discharge port 20 is formed with a discharge port 31 for minimizing the pressure by opening the pressure sensing unit 30 when the discharge port 20 is reversely flowed and the discharge port 31 is provided on the upper surface of the discharge port 31 on the side of the first hinge P The front and rear surfaces 17 and 18 are formed at the edge of the drain plate 20 so that the front and rear surfaces 17 and 17 are separated from each other by the first hinge P1 and the second hinge P1, 18) (19) in a confidential manner.

In order to enhance the airtightness with the discharge port 31, protrusions are formed at the lower part of the open plate 35 at the same or constant spacing as the discharge port 31.

At this time, packings made of a material such as a common silken cone or rubber are bonded to the side surfaces contacting with the drain pan 20 to minimize the release of odors to the atmosphere by increasing airtightness.

According to the present invention configured as described above, a manhole plate formed on a rim of a drainage cover is placed on a step formed at an entrance of a manhole, and a manhole cover such as a drainage cap is placed on the manhole plate. The weights of the weight weights 40 provided in the hollow portion 14a of the split protrusion 14 as in 5a cause the ends of the pair of drain plates 20 to abut the skirts of both sides 18 and 19 Thereby preventing odors generated in the inside of the manhole from being released to the atmosphere, thereby improving the environment around the manhole and minimizing air pollution.

When rainwater or wastewater flowing through the manhole cover flows through the inflow space portion 15 and flows down both sides 18 and 19 to be collected on the drain plate 20 to have a constant load, When a load greater than the weight of the weight weight 40 supporting the drain plate 20 is applied, the drain plate 20 is opened as shown by the chain line in FIG. 4B and smoothly drained. The pair of drain panes 20 are opened downward as far as the solid line so that a large amount of water can be freely discharged at the same time.

After the drain pan is opened and the drain pan is formed, the drain pan is returned to its original position by the weight of the weight weight provided in the hollow portion of the split protrusion, and the end of the drain pan is abutted with the bottom face of both sides as shown in FIG. So that the odor generated from the manhole is blocked.

In addition, when the manhole is smoothly drained as described above, or when the backflow occurs due to the occurrence of an anomaly in the manhole, the drainage plate is supported by the side surface and is not opened, The opening plate 35 is gradually opened from the discharge port 31 of the discharge plate 20 with the second hinge P1 as a starting point so that a part of the backflow pressure flowing backward is reduced, It is possible to minimize the possibility that the cover is detached or broken at the entrance of the manhole.

Therefore, even if the backflow pressure generated in the manhole is considerably high, the backflow pressure is partially discharged while the open plate formed on the drainage plate is opened, thereby reducing the backflow pressure and reducing the great damage.

The open plate which is opened by the back flow is supported by the bottom of the drain hole cover or the manhole cover provided at the upper portion of the drain cover, and after the back flow pressure is reduced, the outlet of the drain plate is naturally covered and closed by its own weight .

Accordingly, it is an object of the present invention to prevent malodors generated from a manhole normally from being released to the atmosphere, to allow the drain plate to be opened and to drain smoothly when draining, and even if a large amount of water is generated suddenly, It is possible to secure a large amount of drainage at the same time as much as possible. In addition, it is possible to reduce the backflow pressure even when backflow occurs and to minimize the separation and breakage. Thus, not only odor can be cut off but also small amount or large amount of drainage can freely be made, It is possible to achieve excellent conditions that can simultaneously perform prevention.

While the present invention has been described with reference to the preferred embodiments described above and the accompanying drawings, it is to be understood that the invention may be embodied in different forms without departing from the concept or scope of the invention. Accordingly, the scope of the present invention is defined by the appended claims, and is not to be construed as limited to the specific embodiments described herein.
